When I first started wearing my topper I just wore it like I wore my own hair only now it looked thicker. But as time went on I realized I could try different styles that with my natural hair I couldn't achieve. Think out of the box and be creative.
In my own experience I waited until I couldn't stand it anymore. My hairline and center part is very thin and with certain light looked terrible. With new topper I feel confident again. You will know when its tome.
